| Posted: 10 Aug 2021 01:13 PM PDT Novel camera detects the birth of high-energy runaway electrons, which may lead to determining how to prevent damage caused by the highly energetic particles. |
| Researchers use artificial intelligence to unlock extreme weather mysteries Posted: 10 Aug 2021 11:31 AM PDT A new machine learning approach helps scientists understand why extreme precipitation days in the Midwest are becoming more frequent. It could also help scientists better predict how these and other extreme weather events will change in the future. |
| Insidious coral killer invading Palmyra Atoll reef Posted: 10 Aug 2021 11:31 AM PDT The reefs at Palmyra Atoll, a small outlying atoll in the equatorial Pacific Ocean, have been undergoing a shift from stony corals to systems dominated by corallimorphs, marine invertebrates that share traits with both anemones and hard corals. Marine biology researchers discovered that although the invading corallimorph is the same species that has been there for decades, its appearance recently changed, and it became much more insidious. |
| Urban experimentation can help develop sustainable policies Posted: 10 Aug 2021 09:11 AM PDT A new study offers an outline of the requirements and research challenges involved in designing effective policies to meet sustainability goals for cities. |
| Ultraprocessed foods now comprise 2/3 of calories in children and teen diets Posted: 10 Aug 2021 08:09 AM PDT Results from two decades of data show ultraprocessed foods have become a larger part of kids' and teens' diets with disparities by race and ethnicity. |
| Speed and absorption key to optimizing new type of rechargeable battery Posted: 10 Aug 2021 07:47 AM PDT Rechargeable, lithium sulfur batteries are promising candidates to sustainably meet the world's energy demands, and a new study has put them one step closer to becoming readily available. |
| Pest attack-order changes plant defenses Posted: 10 Aug 2021 07:46 AM PDT The dining time of different insects impacts a plant's defenses and nutritional quality -- a complexity uncovered in new research with implications for pest management strategies. |
| Cellular filaments keeping the pace Posted: 10 Aug 2021 07:46 AM PDT A new model describes the coordination of beating cilia allowing to predict their functional behavior. Researchers analyzed the formation of metachronal waves in arrays of cilia and how external cues might influence them. The model allows to better understand the crucial role that cilia play in many biological processes and lays the foundation for its manipulation. This may ultimately improve the corresponding medical diagnostics and treatments, but also helps in the design of artificial systems used in microscale engineering. |
| Nitrogen inputs in the ancient ocean Posted: 06 Aug 2021 07:43 AM PDT It was long assumed that cyanobacteria were mainly responsible for fixing nitrogen on early Earth, thus making nitrogen available to the biosphere. Researchers now show that purple sulfur bacteria could have contributed substantially to nitrogen fixation under the conditions prevailing in the Proterozoic ocean. |
